Go after concerning journey home? (6)
I believe the answer is:
return
'home?' is the definition.
(I know that home is a more specific form of the action return)
'go after concerning' is the wordplay.
'go' becomes 'turn' (as in one's go or turn in a game).
'after' is a charade indicator (letters next to each other).
'concerning' becomes 're' (both can mean on a particular topic).
'turn' put after 're' is 'RETURN'.
'journey' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for return that I've seen before include "Interest" , "Retort" , "Yield" , "election to parliament" , "Proceeds" .)
